GONDENSING-APPARATUS PUMP.

Specification of Letters Patent.

Patented Oct. 20, 1908.

Application filed November 25, 1907. Serial No. 403,646.

To all whom it may concern:

Be it known that I, JOHN ASTROM, a citizen oftheUnited States, and resident of Milwaukee, in the county of Milwaukee and State of \Visconsin, have invented certain new and useful Improvements in Condensing-Apparatus Pumps; and I do hereby I declare that the following is a full, clear,

and exact description thereof.

My invention consists in what is hereinafter particularly set forth with reference to the accompanying drawing and pointed out in the claims, its main object being to provide simple, economical and efficient pumps for the separate removal of air and "water from. steam condensing chambers and posed bctweeu said pump-base and the chambers.

The wall of the chamber B is provided with an inlet I; for steam to be condensed, and the upper portion of said chamber is provided with an inlet (1 for injection-water, as well as an outlet 01 for accumulated air.

This upper portion of the chamber B is also provided with a pan ,bottom 6 having a vertical flange f around a ccntralaperture of same, and suspended from the pan is a tray (y ap 'iroximately midway between said pan and another pan k that is supportedon lugs 2 in said chamber, the latter pan being provided with a vertical flange j around a. central aperture therein.

The valve-plate l) carries a series of valves m that open from the chamber B into the pump-base A and close in the opposite direction, any suitable form of valve being employed. The wilve-plate l l carries a series of valves a similar to those aforesaid but arranged to open from the pumpbase into the chamber 0 and close in the opposite direction. The outlet of the chamber 0 is -providcd with an inwardly ext-ending flange 0 whereby a cushiomspace is formed within said chamber m the hpper portionof same. A cylinder F extends into the waterchamber base A aforesaid through one end of same and an outer flange p of t e cylinder 'is made fast tosaid base, the joint being water-t1ght-. The inner end of the cylinder '15 open, and its outer end is connected to.

holloiv head G, which head is providedwith a partition (1 by which it is divlded into com 'artments having valve-controlled o enin'g's y which communication is establis ed between these compartments and said cylinder. The head-compartments are closed by covers 1", s, and the valves t, a, controlling the communication between the cylinder 1 and'said head are of any suitable construction. The valve it opens into the cylinder and the valve a opens in theopposite direction. The upper end of the chamber B has pipe-connection H with the cylinder-head compartment. containing the valve t,' and the other cylinder-' 76 head compartment containing the valve is provided withan outlet w.

In sliding fit with the cylinder F is a. solid plunger I to which is attached a rod J that extends through a stuffing-box m and a gland 3 the stuffing-box being in connection with an end of the water-chamber base A aforesaid. Reciprocative motion is imparted to the rod and plunger by any suitable means.

Injectioirwater enteringthe chamber B,

through the inlet 0, falls in a sheet from the pan c-to the tray 1, thence to the pan h and finally into that portion of said chamber into which steam is admitted through the inlet 7), the 1 result being .a condensation of said steam, the water-of-condensation falling to the bottom of the aforesaid chamber.

When the plunger 1 is pushed into the cylinder F, the volume inside of the waterchamber pump-base A is correspondingl enlarged and the valves m are unseate whereby the water-of-coudensation 1n the chamber B is drawn into said base, but the valves a remain seated. The reverse movement of the plunger proportionately decreases the volume inside the pump-base, and

the pressure thus created causes the valves m to seat and the valvesn to unseat, the water displaced by said plun er being admitted to the overflow-chamber 1 from which it finally escapes through the outlet of same. When this last described movement of the plunger takes place, the space between the same and the head G is enlar ed, the suction thus created causing the va ve t to unseat, whereby accumulated air from the chamber B is drawn into the cylinder, the valv'e it remaining on. seat. However when the first described movement of the plunger 1s repeated, the valve 2? seats and the valve n is unscuted, the air in the cylinder ahead of said plunger being forced into the outlet compartment of the head G to escape therefrom through the outlet to of same.

From the foregoing it will he understood that the reciprocation of the plunger of the herein descrilmd pump will result in the re move] of '2: .er and air separately from the condenser-chaniher \ritlniut commingling of said air and water in the pump itself that is provided with separate inlets and outlets for the aforesaid air and Water. This sepa ate rel: oral of air and water from the condensingthumber results in an undisturbed desirable vacuum in said chamber, and said pump is also capable of use for separating; gaseous and liquid fluids accumulating in any receptacle to Which it may be properly connected,

I claim:

1. A pump com n'ising :1 liquid fluid chamber having valve controlled inlet and an outlet a cylinder having {111 open end in connection with the chamber and provided at its opposite end with a valve-controlled inlet and outlet head for gaseous fluid, and a displacement plunger reciprocative in said l lu l s iiinuntcs li 'guitl lluid al inlet and id in con-- etl 'nt its ded into A pump comprising :1 illlltl fluid.

chamber liming u valverontmlled inlet and outlet, an overflow chamber surrouiuling the outlet of the one aforesaid, 2: cylinder having an open end in connection with the first chamber and provided at its opposite end with a 'ulvecontrolled inlet and outlet head for gaseous fluid, and a disphuicement plunger reciprocstive in said liquid liluid chamber and cylinder but which separates the con tents of same.

In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee in the county of Milwaukee and State of W'iscousin in the presence of two Witnesses.
